No local DataSource found for configuration - dataSource property must be set on LocalSessionFactoryBeanorg.hibernate.HibernateException: No local DataSource found for configuration - dataSource property must be set on LocalSessionFactoryBean. This happens when an action like HQL execution, translation, etc., that needs a DB connection, triggers the creation of the Hibernate runtime environment from Spring, by first time, even if a data source bean is properly configured. Once the environment is already created any action requiring a DB connection works correctly.
